  • Hydrophilic fleeces are used as cover fleeces, i.e. as the top one Fleece or as an intermediate fleece multi-layer fleece, for baby diapers, Incontinence products and similar products used. Such fleeces have the task of body fluids like urine quickly to the absorption layer underneath forward. Ordinary hydrophilizing preparations are due to the liquid transport within the diapers or other products more or less quickly and more or less washed off the fleece. It loses the cover fleece gradually becomes hydrophilic and because of the hydrophobic properties of polyolefins, more and more hydrophobic. The following others Contact with body fluid will pass it on the absorption layer becomes more and more difficult and eventually quite impossible. The result is that the liquid from the Product expires with little or no retention and that the product its original function, the skin of a Keep babies or a patient dry, no more can exercise.
